Abstract

BACKGROUND: Catheter ablation in pediatric patients remains technically challenging. The RHYTHMIA high-density mapping system is increasingly used in pediatric electrophysiology; however, procedural experience in patients weighing less than 20 kg is limited. METHODS: We retrospectively analyzed 125 pediatric patients who underwent catheter ablation for supraventricular arrhythmias using the RHYTHMIA system. The patients were divided into two groups according to body weight: ≥20 kg group (n = 111) and the
